We stayed at Chairat's place for 4nights, from the airport to here will take you about 45mins by taxi (because of the massive traffic), if you get a train probably around 25mins you will arrive at the apartment.
We arrived quite late (9.30pm) Mr Chairat was waiting for us, communication was no problem.
The apartment is so nice! He has it all. Such as washing machine, freezer, sofa, microwaves and etc. The room and bed are so comfortable to sleep and just nice to locate us! I know that Thailand is quite hot, but the room can be cold in a second.
The location. This apartment is just a hundred few metres away from the MRT, and its easy to go to Chatuchak Market/park, transportation to go to one and another is not a problem at all. All in all, Mr Chairat he is a nice man and his apartment is really good. Completely just nice! Hope I can return again to the same apartment next time.
